The proof-of-concepts (PoCs) of FANTASTIC-5G aim at demonstrating the feasibility and the superiority of selected FANTASTIC-5G air interface technologies. This third and last deliverable of WP5 (D5.3) presents the integration of the developed PoC components into the final PoC platforms. It describes the integrated platforms, the evaluation results and the final measurements. To that end, the deliverable starts by briefly revising part of the scenarios and main PoC building components provided in the previous two deliverables (D5.1 and D5.2) in order to provide a complete picture of the integrated platforms. Then, the deliverable presents the evaluation results and the main outcomes of the different PoCs. The different PoCs are classified and presented in three main categories: (1) Prototyping for post-OFDM waveforms, (2) Evaluation of waveform coexistence aspects, and (3) Development of an SDR-based demonstration for broadcast and multicast transmission.

DR2.3 summarizes the results of work package WP2 (System Requirements, Integration, and Evaluation). In the first part (Section 2), we analyse and assess the technical components from work packages WP3 and WP4. We highlight the advantages and disadvantages of each technology and discuss interdependencies and tradeoffs. We also discuss how the technologies address the main project goals, The second part (Section 3) shows the results of the system level simulation campaigns. We evaluate how the proposed technologies perform with respect to the FANTASTIC-5G use cases and requirements. The simulations demonstrate the flexibility and performance of the proposed air interface within a multi-service environment.

This deliverable details how technical components proposed in work packages WP3 and WP4 have been pre-selected and integrated for each of the 5 identified core services into service specific air interfaces in order to prepare the final phase of integration into a flexible and multi-service air interface. Moreover the document presents the first evaluation results of selected technical components. The final selection of technical components will be based on these implementation results. Finally a complete description of the link2system models is given.

This deliverable provides the conclusions of the action by pointing out the key scientific results achieved in FANTASTIC-5G and provides the set of recommendations we can draw from those for the definition of 5G New Radio. Additionally, the deliverable provides a summary of the exploitation and dissemination activities and the impact of the project. In agreement with the project officer we have combined the two project deliverables D6.2 and D1.2 into a single document as they are both covering the same period (the whole project) and are covering complementary areas: the overview of the results and their exploitation and dissemination, the conclusions of the action and the socio-economic impact of the action.

After the completion of Task 5.1 related to the identification of the scenarios and key technical components of the different FANTASTIC-5G proof-of-concepts (PoCs), the research activities of WP5 have focused on the hardware/software implementation of these components and scenarios to demonstrate their feasibility and superiority in the context of the foreseen 5G air interface.
Therefore, this second deliverable of WP5 describes the proposed implementations and algorithm/architecture optimizations of the identified key components as well as the associated results and PoC intermediate version setup and outcomes.
The implementation of PoC component activities are grouped and presented in three main categories: (1) Prototyping for post-OFDM waveforms, (2) Evaluation of waveform coexistence aspects, and (3) Development of an SDR-based demonstration for broadcast and multicast transmission.

The Fifth Generation (5G) of cellular communications will support a plethora of services, devices and mobility patterns. The driving force behind 5G is the five core services considered in Fantastic-5G, namely:
- Mobile BroadBand (MBB)
- Massive Machine Communications (MMC)
- Mission Critical Communications (MCC)
- Broadcast/Multicast Services (BMS)
- Vehicle-to-vehicle and vehicle-to-infrastructure communications (V2X)
A substantial degree of innovation is required to accomplish a common air interface capable of supporting the heterogeneous needs of these core services. To that end, in this document we describe the final results and innovations obtained in Work Package 4 in three major areas: (i) “Context Information and Radio Resource Management”; (ii) Advanced Connectivity Options; and (iii) Spectral Efficiency boosters. The proposed features within these three areas forms the projects network design proposal for a multi-service capable air interface design.

The FANTASTIC-5G project advocates a single air interface for 5G, which is flexible, versatile, scalable and efficient in order to address the requirements of the IMT 2020. The flexibility featured by the FANTASTIC-5G air interface allows the support of a multitude of services and applications with diverse requirements, and shall be ready to provide solutions for future use cases not yet foreseen. This document reports on the recent outcomes of the research on link design, which are presented in a concise form, including a summary of the research motivation, the final outcomes and topic conclusions. The involved topics include the signal design as well as the framework of frame and physical layer procedure design, which provides a quite complete concept of a holistic physical layer air-interface design for future 5G system.

This deliverable defines the use cases, Key Performance Indicators (KPIs) and corresponding requirements, in order to provide guidelines and references for all Work Packages within the framework of FANTASTIC-5G. Furthermore, the functional building blocks of the anticipated 5G air interface are analyzed. Finally, the implementation of the project’s two system-level simulators is described. This includes the calibration of the simulators, as well as the selection of parameters and models.

A substantial degree of innovation is required to accomplish a common air interface capable of supporting the heterogeneous needs of these core services. To that end, we describe the intermediate results and innovations obtained in Work Package 4 in three major areas: (i) “Context Information and Radio Resource Management”; (ii) Advanced Connectivity Options; and (iii) Spectral Efficiency boosters.

The proof-of-concepts (PoC) in FANTASTIC-5G target to implement key technical components developed within the project. The demonstration aims at validating the feasibility and the superiority of the different components of the foreseen 5G air interface.
For this activity, several platforms are being developed in FANTASTIC-5G. The planned demonstrations are categorized into three main categories: post-orthogonal frequency division multiplexing (OFDM) waveform prototyping, coexistence aspects evaluation and broadcast and multicast software defined radio-based PoC.
This deliverable aims at identifying PoC scenarios envisaged in the project. As a consequence, it will provide the necessary information on the approved scenarios and selected techniques. Additionally, it provides a description of the available/to be developed software and hardware platforms.

FANTASTIC-5G advocates a single air interface for 5G, which is flexible, versatile, and scalable in order to address the requirements of the beyond 2020 era. The flexibility of FANTASTIC-5G
air interface allows the support of a multitude of foreseen and unforeseen services/applications with diverse requirements, such as Mobile Broadband (MBB), Massive Machine Communications
(MMC), Mission Critical Communications (MCC), Broadcast/Multicast Communications (BMS) and Vehicular to anything communications (V2X).
The scope of this Work Package is the link design which focuses on the PHY and MAC layer research. The objective is to provide a holistic link solution that can be flexibly adapted to five core services
(MBB, MMC, MCC, BMS and V2X). This flexible adaptation to different services works under the assumption that the air interface has knowledge on the service type of each data flow, paving the way
for efficient cross layer optimization. The main focus of this WP is on the technical aspects that are tightly related to future 5G standardization, rather than a general algorithmic investigation.
This document represents the first deliverable on the link design research in the FANTASTIC-5G project, which presents the project’s preliminary technical research results on the link solutions for a
service-specific air interface design. In this document, we first describe service-specific baseline solutions for the five core services based on 3GPP latest releases with some not-yet-standardized but
straightforward enhancements. After recalling the primary challenges for those services, we provide preliminary results on the service-specific solutions, which will in the succeeding steps be harmonized
towards a holistic air interface design embracing the five core services.

FANTASTIC-5G objectives are:
1. to develop a flexible and scalable multi-service air interface
2. with ubiquitous coverage and high capacity where and when needed
3. being highly efficient in terms of energy and resource consumption
4. being future proof and allowing for sustainable delivery of wireless services far beyond 2020.
5. To evaluate and validate the developed concepts
6. and build up consensus on reasonable options for the standardization of 5G.
The project deals exclusively with lower carrier frequencies (< 6 GHz).

5G will have to cope with a high degree of heterogeneity in terms of services, device classes, deployment types, environments and mobility levels. Consequently, diverse and often contradicting Key Performance Indicators (KPIs) need to be supported, such as high capacity/user-rates, low latency, high reliability, ubiquitous coverage, high mobility, massive number of devices and low cost/energy consumption. 4G is not designed to meet such a high degree of heterogeneity efficiently. Moreover, having multiple radio access technologies for multi-service support below 6GHz will be too costly. FANTASTIC-5G is a European project which will develop a new multi-service Air Interface (AI) for below 6 GHz through a modular design. To allow the system to adapt to the anticipated heterogeneity, the pursued properties are: flexibility, scalability, versatility, efficiency and future-proofness. To this end, the project will develop the technical AI components and integrate them into an overall AI framework where adaptation to the above described sources of heterogeneity will be accomplished. The work will also comprise intense validation and system level simulations. The consortium possesses the main stakeholders for innovation and impacting standardization, maintaining Europe at the forefront.
